VERTlCALLY-PIVOTED WINDOW.

SPECIFICATION forming part of Letters Patent No. 764,955, dated July 12, 1904.

l Application liled April 6, 1904. Serial No. 201,855. (No model.)

of which the sash can be raised.a short dis-- tance to clear the sill or the usual ridges on the sill-strip; and the object of the improvenient is to provide a simple and sensitive lifting mechanism operated by the end wise movement of a wedge-block which will give the Isash a flat support when it is raised for rotating and will also rigidly lock the sash against elevation and rotation when it is closed and lowered, together with a friction pivotal con ncction adapted to be tightened to retard the This object is attained' rotation of the sash.

j by the construction, mechanism, and arrange- 1 ment illustrated 1n the accompanying drawj ings, 1n wh1chally made shorter than the inside clearheight,

Figure 1 is an elevation of a window with the sash closed and lowered; Fig. 21 a similar view, with the sash raised and opened,

illustrating the use of the lifting device; Fig. 3, a fragmentary elevation, with the sash lowered on the sill-strip,showing the lifting device with part of the face-plate removed; Fig. 4, a similar view showing the sash raised and part of 'the sill-strip in section; Fig. 5, a detached perspective view of the case with the wedge-block and the wedge-plate in place and the face-plate separated opposite its place; Fig. 6, a detached perspective view of the wedge-block; Fig. 7, a detached perspective view of the sill-plate with the wedge-plate pivoted and rotated thereon; Fig. 8, a detached perspective View of the sill-plate with the wedge-plate and friction-block separated opposite their places; Fig. 9, a detached perspective view of the `friction-block; Fig. 10, a perspective section on line 10 10, Fig. 4; and Fig. 11, a section on line 11 11, Fig. 4.

Similar numerals refer to similar parts throughout the drawings.

In this classof windows the sash 1 is usuwhich'the sash is pivoted, as at 6.

of the opening of the frame 2, and the ,space between the upper sash-bar 3 and the frame headpiece 1 is partly filled by the 4follower 5, to

The follower extendsv into the upper frame-groove 7, but with the interval 8 between it and the head-piece, so that the sash can be elevated a short distance `to clear the frame-sill 9 or the ridgeslO usually found on the sill-strip 11.

Springs, as 12, are usually provided between 'the follower and the head-piece to press the follower against the upper edge of the sash, and the lower sash-bar -13 is preferably provided with the ridges 14 and 14C", adapted to enter into the grooves formed by the sill-stri p ridges, so that a tight and Vclose joint is made between the sash and the sill-stripwhen the l sash is closed and lowered. The sill-strip is illustrated as being separate from the sill proper and as projecting above it, and this is the preferred form of making the window, especially when an ordinary frame is adapted to receive a verticallypivoted sash; but a separately-formed and upwardly-projecting strip is not essential to the proper working of the lifting device and pivotal connection.

Thevlifting mechanism is located in the case 15, formed or attached in the mortise 16 in the lower sash-bar and preferably flush with the inner face of the sash. The general shape of the case is that of an elongated rectangular socket open below, and its inner wall is preferably formed by the separable face-plate' 17, which extends a short distance below the edge of the sash. The'internal longitudinal ribs 18 are formed on the side walls of the case near the top, and the internal transverse ribs'19 are formed on the end .walls at the bottom of the case. The housing 2O is pro- -vided on the upper side of the case, in which istransversely pivoted the pinion 21, which pinion is rotated by the lever 22, located, preferably, on the inner side of the sash. The wedge-block 23 is located and adapted to travel endwise in the upperpart of the case and is preferably provided with the lateral flanges 24, adaptedto rest and slide on the longitudinal ribs of the case. These ribs and flanges are designed to support the block in roo the proper operation of the mechanism. The transverse fiat bearings are provided on the upper sides at the ends of the wedgeblock and are adapted to abut and slide against the top or upperv wall 26 of the case, and between these bearings is provided the rack 27, the teeth of which are preferably free from any Contact with the top of the case, and this rack is adapted to freely mesh with the pinion, by which means the block is operated endwise in the case by the rotation of the lever. The 4lower side-of the block is shaped to form the longitudinallyfinclined, faces 28 and 28 and the flat faces 29 and 29", adjoining the lower ends thereof, and the intervening cavity 430 is shaped to form the transverse flange 30, the lower side of which is an extension'of the flat face 29. the block is preferably provided the web 30", which occupies the space below'the case-rib on that side and is used to connect and strengthen the depending parts of the block..

The upper side of the wedge-plate 31 is shaped to form the inclined faces 32 and 32,

on which the inclined faces of the block are adapted to slide, and the fiat faces 33 and 33", adjoining the upper ends thereof, on which the fiat faces of the block are adapted to rest when the block is moved endwise to the left end of the -case, as shown in Figs. 4 and 5, and the intervening cavity 34 is shaped to form the transverse flange 35, the upper side of which is in extension of the fiat surface 33, which fiange is adapted to lap over and engage the corresponding flange 30 of the fblock when'the block is moved endwise to the Sright of the case, as shown by broken lines in Fig. 3. To permit thedirect endwise move- "ment of the block necessary for the blockflange to enter under the plate-flange, the flat faces 29 and 29* on the bottom of the block are made shorter than the fiat faces 36 and 36* at the vbottom of the inclined face of the plate. On the side of the wedge-plate opposite the wedge-block web .is preferably provided the web 37, which occupies the space below the 'case-rib on that side and is used to connect and strengthen the projecting upper parts of the plate. The depending pivotpost 38 is provided on the wedge-plate, preferably midway between its ends, in which post is formed the annular groove 39, and the ribs 40 fare provided on the ends of the plate, which ribs are adapted to engage the end ribs of the case, and thereby prevent the plate from dropping out of it.

()n one side of` sEsT AVAILABLE cop* tion of the pivot in the bearing is retarded to any desired extent by the adjustment of these screws. rlhe annular rib 47 is provided on the friction-block in the bearing, which is adapted to fit in the annular groove of the pivot-post and to hold it in its proper place, as shown in Fig. ll-that is to say, with the wedge-plate resting 'on the sill-plate.

The parts being assembled and the sash being closed and lowered, as shown in Figs. l and 3, to raise the sash the lever is thrown to rotate the pinion, asindicated by the arrow in Fig. '3, which rotation moves the wedgeblock from the right to the left end of the case. The first effect of this movement is to carry the transverse fiange of the wedge-block out from under the similar flange of the wedgeplate, afterwhich the inclined faces of the block come in contact with the similar faces 'and proportioned that the final part of the endwise movement of the wedge-block carries the Vfiat faces on its lower side onto and along the corresponding fiat faces on the top of the wedge-plate, which provides a fiat bearing for the sash after it is raised, as shown in Figs. 3 and 4. 'In this'position the entire weight of the sash is carried by the end bearings of the wedge-block abutting against the upper wall IOO of the case, and there is no strain or pressure whatever on the rack or pinion, and especially there is no pressure acting to reverse the rotation of. the pinion to let the sash down, which is necessarily thecase when the sash is sustained on an inclined bearing. When the sash is thus elevated to free the ridges of the lower bar from the ridges of the sill-plate, it is free to be rotated on its vertical pivots, as shown in Fig. 2, subject only to the retarda tion caused by the adjustment of the frictionblock of the lower pivot-bearing. In this rotation the wedge-plate rotates with .the sash, and the weight thereof is preferably carried by this plate resting and turning on the sill-plate. The sash being raised and rotated to-be in line with the sill-strip,as shown in Fig. 4,to lower it the lever is thrown to rotate the pinion, as indicated by the arrow in the same-figure, which rotation moves the wedge-block from the left to the right end of the case. The first effect of this movement is to carry the fiat faces of IIO IZO

the block along and off of the corresponding the similar flange of the plate, which locks the sash against being raised, as by a burglar with a jiminy, without an endwise movement of the block, and when the sash is lowered on the sill-stri p the depending part of face-plate descends and engages along the inner edge of the sill-plate, as shown in Figs. l and 3, which engagement locks the sash against rotation without its being raised.
